What is the cost of change? Roberto Guerra's photo essay "La Carretera: Life and Change Along Peru's Interoceanic Highway" asks viewers to consider the impacts of the 1,600 mile-long highway through Peru and Brazil that connects Pacific...

"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

Global warming has long been in the making. A thorough review of decades of research helps pupils discover the weather patterns of global warming. Learners then connect the weather changes to data in the Keeling Curve that reveals trends...

Scholars connect statistical analysis with flexible electric circuits. They first learn about flexible circuits and their applications through a PowerPoint presentation and then consider how the fabrication process for these circuits...

Which is worse — drought or flooding? Neither is helpful to the environment, and both are increasing due to climate change. The 16th lesson in a series of 21 covers the average precipitation trends for two different climates within the...

Many researchers focus on one impact of climate change in isolation, but researchers gain a global perspective when they come together. A timely lesson teaches scholars about the projected impacts of global temperature increases. Then...

With 90 percent of its land area covered in forests, Suriname, a country in South America, contains the largest percentage of forests throughout the world. Here is an activity that brings classmates together to learn about the...

After cutting down a forest to make a farm, how long would it take the environment to turn an abandoned farm back into a forest? Scholars study this exact scenario while they interpret many charts and graphs of the changing ecosystems as...

Meteorologists view an animated video by the Environmental Protection Agency to learn how the carbon cycle works, and then move into groups to analyze and graph actual data of the atmospheric carbon dioxide concentration from Hawaii's...

Students study how the ocean stabilizes our planet's climates and how global warming is becoming a threat to this fine balance.  In this climate change lesson, students identify that fossil fuel emissions are responsible for...

According to the United Nations, climate change affects every country on the planet. This research project encourages scholars to explore the factors that affect climate change from different perspectives: climate scientist, policy...

Currently, only 2.1% of global warming is felt on continents, while over 93% is felt in the oceans. The fourth lesson in the series of 21 on global warming is composed of three activities that build off one another. In the first...

If you are looking for a great way to present natural selection in humans, look no further. This handout is intended to accompany the 14-minute video The Making of the Fittest: Natural Selection in Humans, which can be found on the...

Take an in-depth look at nutrient loading, eutrophication, and hypoxia using data on The Chesapeake Bay as an example. This comprehensive presentation includes detailed graphs, photos, and details about the changes in marine organism...

Students examine climate change. In this current events lesson, students read the provided articles "Key Facts + Key Conclusions=0?" "Oil Companies Fund Climate Change Deniers," and "Acting on Climate Change Facts." Students respond to...

You've heard of farm to table ... but what about farm in classroom? Junior agriculturalists embark upon a two-week journey into the science of growing things. Based upon the classic terrarium in a two-liter experiment, the lesson goes...

Students investigate the evidence and consequences of global warming. They read and discuss an article, conduct a debate, evaluate their community's climate statistics, log their gas consumption for a week, and develop a panel discussion...

Students identify the most common causes of global warming. In this earth science lesson, students use an interactive website to explore changes over time in sea ice, sea level, carbon emissions, and average global temperature. They take...

How has Gorongosa National Park changed over time? Discover the park's rich history, dating back to primitive human times, through an interactive timeline and scientific reading. The second installment in an eight-part series explores...

The fastest growing volcano in recorded history grew more than 150 meters in less than a week and to more than 424 meters in less than a decade. How do we safely monitor active volcanoes? Young scientists design an...

Can organic molecules come from a pre-biotic environment? Stanley Lloyd Miller proved it is possible when exactly the right conditions exist. Learn about his experiment and the other experiments later building off of it that changed the...

Students investigate the relationship between physical geography and Utah's settlement. In this Utah land lesson, students view a PowerPoint about Utah land and work in groups to answer questions about the uniqueness of Utah's Mormon...

Young oceanographers take a look at sea level data from several cities over a few centuries. They use the data to fuel a discussion about what kind of changes are taking place and the impact they are having on the coastal ecosystems....

Students explore recent changes in the Artic's climate that have been observed by Artic residents. They watch videos, take notes and create a concept map. They also look at historical weather data from a specific Artic community. The...
